TECHNICAL FIELD

The present invention relates generally to a method, system, andcomputer program product for testing code. More particularly, thepresent invention relates to a method, system, and computer programproduct for correlating test result variations with businessrequirements.

BACKGROUND

Data management operations often have to extract the data from one ormore data sources. The extracted data is frequently not in a form thatis suitable for consumption or usage in a given data processing system.Therefore, the data management operations also have to often transformthat data into a consumable form, such as for loading into a repositoryor a database. The process of extraction, transformation, and loading(ETL) of data in a given data processing system is compactly referred toas ETL. Accordingly, a data processing environment where ETL is employedis referred to as an ETL environment.

ETL operations are used in a variety of forms, in a variety of dataprocessing environments, and for a variety of purposes. Databasemanagement is an example of a common circumstance in which ETLoperations are used for extracting data from one or more data sources,including other databases; transforming that data according to somebusiness requirements; and loading that transformed data into one ormore destinations, including reports, workflows, a database, or othersystems.

Typically, a business unit specifies a business requirement for whichdata has to be manipulated in a given ETL environment. A businessrequirement specifies a need or use of certain information in thecontext of a business operation. For example, a business requirement canbe a text document describing a need, a use, a goal, or an objective(collectively hereinafter, “objective”) expected to be satisfied. Thedocument may or may not specify any particular data for this purpose.Even when the data that is usable for this purpose is identified in thedocument, the identified data is insufficient to extract the data from asource, in a usable form, to satisfy the objective.

A team typically translates a business requirement into a technicalspecification. The technical specification describes one or moreoperations that have to be performed with some data, to achieve anobjective of the business requirement. For example, the technicalspecification may specify a data source and a manner of extracting aparticular data therefrom, a transformation that may have to be appliedto the data, and a subsequent computation or storing operation with thatdata to produce a result that satisfies the objective of the businessrequirement.

Software developers implement the technical specification into code. Thecode, when executed on a data processing system, uses the data sourcesto obtain the data, performs the specified operations on the data, andproduces the results.

The code is tested for satisfactory functioning. For example, a testinguser creates one or more test cases for executing the code. The code,when executed according to a test case, produces test results. A userexamines the test results to determine whether the code functioned asexpected, and whether the results generated would satisfy the objectiveof the business requirement.

DETAILED DESCRIPTION

The illustrative embodiments recognize that in a given businessrequirement document, different portions may have different objectives.Accordingly, different code or code-sections implement the technicalspecifications describing the different portions of the businessrequirements.

A typical workflow using the presently available ETL solutions convertsthe business requirements to a technical specification, converts thetechnical specification to code, generates test cases for the code, andexecutes or tests the code according to the test cases to produce testresults.

The illustrative embodiments recognize that in ETL environments, a needexists to not only test every ETL operation, but to also prove that theoperation has been tested. Furthermore, a need exists for relating thetest results with one or more business requirement.

The illustrative embodiments recognize that presently, the only way toprove that the full ETL functionality has been tested is by manuallyreviewing the code corresponding to the business requirement, validatingthat all code is executed during a test, that no errors have beenintroduced in the test result, and that the test results do not deviatefrom the business requirement.

Accordingly, presently, the test results are frequently downloaded intodesktop tools where a user compares the test results with expectedresults. The illustrative embodiments recognize that such a manner ofrelating the results of a test with a corresponding business requirementis error-prone, time consuming, and prohibitive for large volumes ofdata.

The illustrative embodiments recognize that automatically relating thetest results with corresponding business requirement portions isdesirable to reduce the cost, chances of error, and misdiagnosis,especially in ETL environments used in commercial business settingstoday. The illustrative embodiments further recognize that annotatingthe business requirement portions to indicate whether a test resultsatisfied the objective of the business requirement portion within aspecified tolerance, exceeded the tolerance, was absent in the testing,or was otherwise unsuitable for the business requirement portion wouldbe helpful in any remediation workflow.

The illustrative embodiments used to describe the invention generallyaddress and solve the above-described problems and other problemsrelated to automatically relating test results with businessrequirements. The illustrative embodiments provide a method, system, andcomputer program product for correlating test result variations withbusiness requirements.

Within the scope of the illustrative embodiments, relating a result of atest execution of code with a business requirement that corresponds tothe code includes associating the test result with the businessrequirement of a portion thereof. Relating the test with the businessrequirement according to the illustrative embodiments further includesestablishing whether the test result satisfies an objective of thebusiness requirement within a tolerance. Relating the test with thebusiness requirement according to the illustrative embodiments furtherincludes marking or annotating the business requirement or the portionbased on whether the test result satisfies the objective of the businessrequirement within the tolerance.

The annotated business requirements document according to an embodimentwould allow a user to more expeditiously and accurately focus any changeefforts on the portion that has an undesirable annotation, to correct atest result using an existing workflow. For example, suppose that anembodiment highlights or otherwise annotates a portion of the businessrequirements to show that a test result corresponding to that portionwas missing in a test. By having such annotation available, the user cansave a significant amount of effort in trying to identify an area of thebusiness requirements, the technical specification, the code, the testcase, or a combination thereof. The annotation enables the user tointeract with the annotated portion of the business requirement todirectly reach and modify the appropriate business requirement portion,technical specification, the code, the test case so that the test resultis produced in a later test.

Other types of annotations similarly assist the user in locating thebusiness requirements, the technical specification, the code, the testcase, or some combination thereof, in reference to other types of testresult anomalies. For example, a different annotation indicates that atest result corresponding to the annotated portion of the businessrequirements document exceeds a tolerance from the expected value. Theuser can similarly use the annotation to quickly make modifications tothe business requirements, the technical specification, the code, thetest case, or some combination thereof.

An existing integration tool generates the correspondence between abusiness requirements document, the technical specification, and thecode that is generated by the tool. During a test execution of the code,an embodiment marks the beginning and end of a test operation. A testoperation tests a section of the code. The embodiment marks the sectionof the code that was tested between the beginning and the end of thetest operation. Accordingly, the embodiment identifies the portion ofthe business requirement that corresponds to the tested code section andwas therefore subjected to test operation.

An embodiment identifies a test result produced from that testoperation. The embodiment compares the test result with a baselineresult to determine whether the test result matches the baseline resultwithin a tolerance. The tolerance can be defined in any suitable mannerdepending upon the type of the result, the desired accuracy of the testresult, and other considerations.

Depending upon how the test result compares with the baseline result, anembodiment annotates the identified portion of the business requirement.For example, one embodiment color-codes the portion as a part ofannotating the portions. For example, when the test result and thebaseline result match within the tolerance, the corresponding portion ofthe business requirement is color-coded in green. When the test resultexists but does not match the baseline result match within thetolerance, the corresponding portion of the business requirement iscolor-coded in red. When the test result is absent, the correspondingportion of the business requirement is color-coded in gray.

The baseline results can be obtained in a variety of ways depending uponthe testing being performed. In one example embodiment, the testoperation exercises code that has not been previously used—in otherwords, new code. As one example, a business analyst may provide a set ofexpected results as baseline results. As another example, a component ofthe integration tool used for code generation may provide a set ofexpected results as baseline results.

In another example embodiment, the test operation exercises code thathas been modified since a previous use—in other words, a differentversion of existing code. The existing code is regarded as a baseversion and the modified code is regarded as a new version.

An embodiment performs regression testing using the base version and thenew version. Specifically, the embodiment performs regression testing onthose sections of the base version and the new version that have notchanged.

For example, using a change requirement, an embodiment identifies thosesections of the base version that have changed in the new version.Therefore, the embodiment also identifies those sections of the baseversion that have not changed in the new version. The embodimentperforms testing of the unchanged sections of the base version and thenew version to determine whether the test of an unchanged section of thenew version produces a test result that should not vary by more than atolerance value, but does vary, from the result of executing thecorresponding section of the base version under similar circumstances.

To create similar circumstances under which to test the unchangedsections of the base and new versions, an embodiment identifies aconfiguration of a data processing environment where the base version isor was operating. This configuration is referred to as a baseconfiguration. The base configuration includes but is not limited tovalues of environment variables, identity of data sources and manner ofextracting data therefrom, a state of the extracted data and existingdata at a given time in the base configuration, processes executing in asystem, and so on.

An embodiment configures a first data processing environment accordingto the base configuration. The embodiment configures the base version toexecute in the first data processing environment. The embodiment furtherconfigures a second data processing environment according to the baseconfiguration. The embodiment configures the new version to execute inthe second data processing environment. Configured in this manner, thebase version and the new version are expected to experience similarcircumstances, access similar data sources, extract similar data, findsimilar states of data, experience similar performances, and so on.

The embodiment executes an unchanged section of the base version in thefirst data processing system to produce a base result. The base resultis treated as a baseline result. The embodiment executes an unchangedsection of the new version in the second data processing system toproduce a test result. The comparing of the results and the annotationthereafter follows in a manner described earlier.

A method of an embodiment described herein, when implemented to executeon a device or data processing system, comprises substantial advancementof the functionality of that device or data processing system inrelating code execution results with business requirements. For example,where prior-art stops at generating a test result and fails to establishthe relationship between the test result and the business requirementthat is expected to be satisfied by the result, an annotates thebusiness requirement related to the result. Furthermore, an embodimentannotates in a way that is indicative of a suitability, unsuitability,or absence of the test result. Operating in a manner described herein,an embodiment allows a user to make modification decisions relative tothe test results more expeditiously and accurately than the prior-art.Such manner of automatically relating test results to businessrequirements is unavailable in presently available devices or dataprocessing systems. Thus, a substantial advancement of such devices ordata processing systems by executing a method of an embodiment allows auser or a decision making process to expeditiously and accurately actupon the business requirements or other artifacts in an ETL environmentthat relate to certain test results, where a manual task according tothe prior-art would be prohibitive due to the complexity or size of thedata processing environment or the artifacts therein.

The illustrative embodiments are described with respect to certain dataor information, sources and repositories, databases, documents orportions thereof, code or sections thereof, result sets, operations,configurations, annotations, tolerances, devices, data processingsystems, environments, components, and applications only as examples.Any specific manifestations of these and other similar artifacts are notintended to be limiting to the invention. Any suitable manifestation ofthese and other similar artifacts can be selected within the scope ofthe illustrative embodiments.

Furthermore, the illustrative embodiments may be implemented withrespect to any type of data, data source, or access to a data sourceover a data network. Any type of data storage device may provide thedata to an embodiment of the invention, either locally at a dataprocessing system or over a data network, within the scope of theinvention.

Not all inputs are necessary for the operation of application 302described herein. For example, business requirements 306 may be suppliedto application 302 when annotated business requirements are desired asoutput 316. An embodiment can annotate other artifacts in an ETLenvironment's workflow. For example, an embodiment can annotate atechnical specification by relating a portion of the technicalspecification with a test result in a manner similar to annotating abusiness requirement portion. Accordingly, technical specification 308may be supplied to application 302 when an annotated technicalspecification is desired as output 316.

An embodiment can annotate multiple artifacts in an ETL environment'sworkflow. For example, business requirements 306 and technicalspecification 308 may both be supplied to application 302 when anannotated business requirements and an annotated technical specificationis desired as output 316.

In addition, application 302 can annotate code 310 in a similar manner.Although certain test tools are able to highlight a code section thatproduced a certain output, such highlighting does not relate the outputback to the business requirements. Thus, when application 302 is used toannotate code 312 in conjunction with annotating business requirements306 and/or technical specification 308, a user has significantly moreinformation to modify one or more artifacts in the ETL workflow in amore efficient and automated manner.

Component 324 executes code 310 according to one or more test cases 314in a test environment constructed according to configuration 304.Component 324 marks the beginning and ending of a test operation on code310, and identified the code section that was subjected to the testoperation to produce a test result.

Component 326 validates the test result using a result in baselineresults 314. For example, component 326 determines whether the testresult matches the corresponding baseline result 314 within a definedtolerance.

When a code section is not executed or the code section encounters anerror, the code section may to produce any test result. Accordingly,component 326 determines that the test result is absent, or the testresult does not match the corresponding baseline result 314 within adefined tolerance, depending upon the output of component 324 or howcomponent 326 is configured to output a result of the matching.

Using the outcome of result validation in component 326, component 328annotates one or more artifacts of the ETL workflow according to thecode section identified by component 324. For example, if the artifactis business requirements 306, component 328 produces one or moreannotated portions of business requirements 306 in output 316.Similarly, if the artifact is technical specification 308, component 328produces one or more annotated portions of technical specification 308in output 316. If the artifact is code 310, component 328 produces oneor more annotated sections of code 310 in output 316. When more than oneartifact is provided, component 328 can select one, some, or all suchartifacts for annotation and presentation in output 316.

With reference to FIG. 4, this figure depicts a block diagram of anotherexample configuration for correlating test result variations withbusiness requirements in accordance with an illustrative embodiment.Application 402 is an example of application 302 in FIG. 3.

Application 402 is configured to perform regression testing on thosecode sections that have not been changed between two or more versions ofcode. As described elsewhere in this disclosure, base environmentconfiguration 404 is a configuration of a data processing environmentwhere the base version of a code is or was executing.

Base version 405 is the base version of code according to a version of abusiness requirement. Base version 405 is changed or modified into newversion 407 according to change specification or change requirement 409.Test cases 412 are one or more examples of test cases 109 in FIG. 1.

Component 418 uses base environment configuration 404 to configure oneor more data processing environments that duplicate or mirror the dataprocessing environment where base version 405 is or was operating. Forexample, component 418 configures a first duplicate data processingenvironment according to base environment configuration 404 to executebase version 405 and configures a second duplicate data processingenvironment according to base environment configuration 404 to executenew version 407.

Component 420 identifies one or more sections of code that have changedin base version 405 and new version 407 according to change requirement409. Application 402 does not regression test these sections.

The remaining sections in base version 405 and new version 407, byimplication, are sections that should not have changed from base version405 to new version 407. Component 425 in execution engine component 424executes one or more of these unchanged sections of base version 405 andnew version 407 in parallel according to one or more test cases 414.Parallel execution of sections of base version 405 and new version 407causes both executions to proceed under similar circumstances in theirrespective duplicated data processing environments, using the same datasources, data states, processes, and other configurations according tobase environment configuration 404.

Component 427 in result validation component 426 validates a test resultproduced from an unchanged section of new version 407 in a duplicateddata processing environment. Specifically, component 427 compares thetest result with a result produced from the parallel execution of acorresponding unchanged section of base version 405 in anotherduplicated data processing environment. Component 325 determines whetherthe test result matches within a defined tolerance the correspondingresult from the parallel execution of the corresponding unchangedsection of base version 405.

As in application 302 in FIG. 3, when a code section is not executed orthe code section encounters an error, the code section may to produceany test result. Accordingly, component 427 determines that the testresult is absent, or the test result does not match the correspondingbase version result within a defined tolerance, depending upon theoutput of component 425 or how component 427 is configured to output aresult of the matching.

Using the outcome of result validation in component 427, component 728annotates one or more artifacts of the ETL workflow according to thecode section identified by component 324. For example, in the depictedexample, the artifact is a version of code that was expected to beunaffected by change requirement 409. Component 428 produces one or moreannotated sections new version 407 in output 416. Because a section ofbase version 405 or new version 407 is relatable to a businessrequirement, component 428 can also annotate the business requirement, atechnical specification corresponding to the business requirement, or acombination of these and other ETL environment artifacts in the mannerdescribed elsewhere in this disclosure.

With reference to FIG. 5, this figure depicts a flowchart of an exampleprocess for correlating test result variations with businessrequirements in accordance with an illustrative embodiment. Process 500can be implemented in application 302 in FIG. 3.

The application configures a test operation to execute on a given code,e.g., new code, in a data processing environment configured for testing(block 502). The application receives, locates, identifies, or otherwiseaccesses a business requirements document related to the code beingtested (block 504). A business requirements document is an artifact thatappears upstream from the testing operation of block 502 in an ETLworkflow. Hence, a business requirements document is an upstreamdocument for the purposes of block 504.

Similarly, a technical specification, the code, and a test case are alsoupstream from the testing operation of block 502. Therefore, a technicalspecification, the code, and a test case are also upstream documents forthe purposes of block 504. Optionally, the application also receives,locates, identifies, or otherwise accesses one or more of these otherupstream documents (block 506).

The application receives a set of baseline results (block 508). Theapplication executes the test operation (block 510). The executing ofthe test operation in block 510 also marks the beginning and endingpoints of the test in the code that is executed.

The application compares a result of the test with a correspondingbaseline result in the set of baseline results (block 512). Theapplication determines whether the test result and the baseline resultmatch within a tolerance (block 514).

If the test result and the baseline result match within the tolerance(“Yes” path of block 514), the application proceeds to block 520 andcontinues executing process 500 therefrom. If the test result and thebaseline result do not match within the specified tolerance (“No” pathof block 514), the application identifies a portion of an upstreamdocument that is associated with the section of the code that producedthe test result, e.g., a portion of a business requirements document ora technical specification, or portions in a combination of these andother upstream documents (block 516).

The application marks or annotates the one or more portions in one ormore upstream documents according to the nature of the mismatch in block514, the degree of the mismatch in block 514, or both (block 518). Forexample, an error in the test result, a missing test result, a mismatchexceeding the tolerance, are some example mismatch conditions that canproduce different annotations in block 518. Any suitable type ofannotation and a manner of presenting the annotated portions to a usercan be used with an embodiment without departing the scope of theillustrative embodiments. For example, one type of annotation mayhighlight a portion in different colors or shades depending upon thetype of mismatch in block 514. Another example type of annotation mayhighlight a portion in different fonts or font sizes depending upon thetype of mismatch in block 514. Another example type of annotation mayposition a portion differently in a display depending upon the type ofmismatch in block 514. Many other ways of annotating portions ofupstream documents and presenting the annotated upstream documents to auser will become apparent from this disclosure to those of ordinaryskill in the art, and the same are contemplated within the scope of theillustrative embodiments.

The application determines if more test results are to be validated inthis manner (block 520). If more test results are to be validated (“Yes”path of block 520), the application returns process 500 to block 512 toselect and validate another test result. If no more test results are tobe validated (“No” path of block 520), the application presents theannotated portions to a user. The application ends process 500thereafter.

With reference to FIG. 6, this figure depicts a flowchart of anotherexample process for correlating test result variations with businessrequirements in accordance with an illustrative embodiment. Process 600can be implemented in application 402 in FIG. 4.

The application receives a base version and a new version of code forregression testing (block 602). The application marks the known changedcode sections in the base version and the new version according to achange specification or change requirement document (block 604).

The application determines a configuration of a base data processingenvironment (block 606). The application creates a duplicate of the basedata processing environment to execute the marked base version of thecode (block 608). The application creates another duplicate of the basedata processing environment to execute the marked new version of thecode (block 610).

The application executes, in parallel, an unchanged section of themarked base version in the first duplicate data processing environment,and executes a corresponding unchanged section of the marked new versionin the second duplicate data processing environment (block 612).

The application obtains a baseline result from the execution of theunchanged section of the base version in the first duplicate dataprocessing environment (block 614). The application obtains a testresult from the execution of the corresponding unchanged section of thenew version in the second duplicate data processing environment (block616).

The application compares the test result with the corresponding baselineresult (block 618). The application determines whether the test resultand the baseline result match within a tolerance (block 620).

If the test result and the baseline result match within the tolerance(“Yes” path of block 620), the application proceeds to block 626 andcontinues executing process 600 therefrom. If the test result and thebaseline result do not match within the specified tolerance (“No” pathof block 620), the application identifies a portion of an upstreamdocument that is associated with the expected unchanged section of thenew code that produced the mismatched test result, e.g., a portion of abusiness requirements document or a technical specification, or portionsin a combination of these and other upstream documents (block 622).

The application marks or annotates the one or more portions in one ormore upstream documents according to the nature of the mismatch in block620, the degree of the mismatch in block 620, or both (block 624). Theapplication determines if more test results are to be validated in thismanner (block 626). If more test results are to be validated (“Yes” pathof block 626), the application returns process 600 to block 618 toselect and validate another test result. If no more test results are tobe validated (“No” path of block 626), the application presents theannotated portions to a user. The application ends process 600thereafter.
